I had a copy on DVD after it was first released and found them all. But after losing it (I loaned it to someone and don't remember who and never got it back) I bought a Blu Ray copy to replace it. And when I watched it in high def for the first time (which was awesome) I then went to verify that the easter eggs were still there.
Also, not an easter egg per se, but did you notice that in the opening sequence there's a quick flash of the Dharma Initiative logo in the bottom right corner of the screen? Specifically, the Pearl Station logo is displayed.
- Go to chapter selection for 13-16, then press up to highlight it. After sitting on that for 77 seconds a new chapter selection comes up for chapter 17.
- This contains "Supplemental Files" which include additional videos collected by the DOD:
- #USGX-8810-B467-144VD: Videos recorded by Jami Lascano (the cute chick who can be seen passed out on the during Rob's going away part) to her boyfriend Teddy, who was in Japan at the time.
- Only video 2, 5, 9 and 11 are playable. In the last one, when she's very hyper, she mentions going to Lily's part (the one for Rob).
- #USGX-8810-B467-34VD: If you select the right-most oval on the Slusho screen then you'll see a very Japanese commercial for Slusho.
- In scene selections, select scene 10 and click up twice. You'll see a red X appear. Select it and you can see the pre-CGI effects version of the tun scene. It includes giant Xs on the actors to represent where the parasites are going to be placed in the final product.
- Go to languages, select "Spanish" for subtitles and then click right. You'll see a big red helicopter appear. Selecting that takes you to a video of the cast and crew having fun saying "Rack 'em and pack 'em, we're phantoms in 15!"
